1. Troubleshooting
If DDM cannot work with your monitor, DDM will show below icon in your notification tray.
Click on the icon, DDM shows a more detailed error message.
Please note that DDM only works with Dell branded monitors. If you are using monitors
from other manufacturers, DDM doesn’t support them.
If DDM is unable to detect and/or communicate with a supported Dell monitor, please take
below actions to troubleshoot:
2. Ensure the video cable is connected properly to your monitor and your computer,
Check the connectors if they are rmly connected in place.
3. Check the monitor OSD to ensure DDC/CI is enabled.
4. Download and install the latest graphics driver from the manufacturer such as Intel,
AMD, and NVIDIA. DDM often fails in the absence of the latest graphics driver.
5. Remove any docking stations or cable extenders or adapters between the monitor
and the video port. Some low-cost extenders,hubs or converters may not support
DDC/CI properly and can be the reason for DDM failure. Update the driver of such
devices if the latest version is available.
6. Restart your computer.
